We confirmed the nuclear localization of CX3CL1 with orthogonal projections of confocal microscope-obtained z-stacks Figure 1B10, as well as Western blot from the isolated nuclear fraction from IPF lung fibroblasts, assayed with an anti-CX3CL1 antibody (Figure 1B11). Here, CX3CL1 is linked to idiopathic pulmonary fibrosis.
